Use Pascal's triangle to find the coefficient of the third term in the expansion of (a + b)^2. a. 3 b. 4 c. 2 d. 1

d

Step-by-step explanation:

Hello,

Let's compute the first lines of Pascal's triangle

1

1 1

1 2 1

so the third term in the mentioned expansion is 1

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
